3.2.1
Communication with other Stations
3.2.1.1 Protocol Elements
The communication function controls the transmission of messages via protocol elements to
other automation units or control systems.
A protocol element is based on hardware integrated in the Master Module for serial or
LAN/WAN communication, and supports protocols according to IEC 60870-5-101/103/104, as
well as various protocols for the communication with third-party systems.
Communication in Transmit Direction
•
The messages to be transmitted are learned through the automatic data flow routing and
stored in the data storage
•
The transfer of the messages from the data storage to the protocol elements takes place
via a priority control in order to optimally utilize the transmission route
Communication in Receive Direction
•
Messages with process information
are distributed to all functions within the automation unit
•
Messages with system information
are either processed directly (example: station interroga-
tion) or distributed further based on their destination address (CASDU) (example: mes-
sages for remote maintenance)
